Really struggling with this code 20

[KnappAttack]

Changed both MAP sensors with working sled. Checked all wires and connections and am still getting a code 20 with flashing yellow warning. Any one have anything that might help? Trying to get ready to leave for UP on Wed next week. Ran fine on dyno. Pulled it off and now have this code 20 flashing. Thought it just could be a stuck code and used HAMMERS sticky above on how to get rid of the codes to no avail. Mike Knapp#17

Thanks ultimate. I talked with Jeff Simon last night and he told me to do about the same thing. I just disconnected the efi controller, reconnected the stock wires, and got rid of the code. Also put back on original sensors and all seems good again. It pays to ask. Thank You!!!
